Hi,
I'm about to buy a house. The home survey reported:
"Using my moisture meter I tested the chimney breast to the ground floor and first floor and through the loft space. The chimney breast to the front of the house was dry on all elevations. The rear bedroom chimney breast tested positively for damp. The moisture is not causing blistering to the plaster or unsightly staining however the moisture is likely to be as a result of condensation formed from either cold bridging within the stack or possibly hygroscopic salts which attract moisture from the environment. The installation of an air vent in the chimney breast would likely remedy this."
However, we went to view the property again last week whilst it was raining and had rained a lot during the week to find some damp patches on the chimney breast in the loft bedroom.
I've attached photos of the damp patches and also google earth images of the loft conversion. Could the damp patches be due to a leak on the roof? Could this be causing the damp all the way down, or could this be a different issue, and both leak and air vent needs to be sorted?
Oh and the house is 1930's build.
Many thanks
Russ
